VALVE-OILER.

SPECIFICATION forming part of Letters Patent No. 294,898, dated March11, 1884. Application filed December 21, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, SAMUEL DAVIES MER- SHON, of Rahway, in the county ofUnion and State of New Jersey, have invented a new and usefulImprovement in Reciprocating Valve Oilers, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inallthe figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is anelevation of the same turned one-quarter around from the po sition shownin Fig. 1. Fig. 3 is a sectional plan view of the tubeand'discharge-rod, taken through the broken line xx 00 m, Fig. 1. Fig. 4is a longitudinal section of the dischargerod.

The object of this invention is to facilitate the oiling of engines,shafts, and other bearings and moving parts of machinery, and also tosecure regularity in the amount of oil delivered.

The invention consists in an oiler constructed with an oil-reservoirprovided with a tube having an opening in one side, and a jointeddischarge-rod having a recess in one side, and moved forward and back bya crank-shaft driven by a ratchet-wheel, pawl, and vibrating pendulumorlever. The swing ofthc pendulum, and consequently the rapidity of feed,are regulated by set-screws passing through the inwardly-inclinedupperends oftwo standards attached to the top of the oil-reservoir. Theoil-discharging rod is madein two parts,halved to each other, connect-edadjustably by screws, and having a recess between the end ofv one partand the shoulder of the other part, so that the size of the said recesscan be readily regulated, as will be hereinafter fully described.

A represents the oil reservoir or cup,through the center of which passesa tube, 13. The tube B may be formed solid with the top of thereservoir, and screwed into ascrcw-hole in the bottom of the saidreservoir, or screwed in place in any other suitable manner. Oil isintroduced into the reservoir A through an opening in its top, whichopening is closed by a screw-plug, 0, having a perforation, D, formedthrough it to admit air to the said reservoir,

50 to take the place of the oil as it is discharged.

In one side of the lower part of the tube B is formed an opening, E,through which oil can pass into the interior of the said tube and enterthe poclmt or recess F in the side of the rod G, fitted accurately intothe said tube. Therecess or pocket F is formed between the end of themain part of the rod G and the shoulder of the extension part G of thesaid rod. The main and extension parts of the said rod G are halved toeach other, and are held in place by screws H, which pass through shortslots in the extension part G and screw into the main part G. The outerparts of the slots in the extension part G are countersunk to receivethe heads of the screws H, so that the said heads will be flush with theouter surface of the said rod. \Vith this construction,when

the rod G is raised, the recess F comes opposite the opening Eandbecomes filled with oil. As the rod G moves downward, the oil in therecess F is carried with it and flows out through the lower part of thetube B to the surface to be oiled. The bore of the lower part of thetube B is enlarged opposite the recess F, where the rod G is at thelower end of its stroke, as shown in Fig. 1, so that the oil can flowout of the recess F freely. The upper part of the rod G is jointed, andits upper end is pivoted to a crank, I, formed upon the shaft J, whichrevolves in bearings in the upper ends of the standards K, attached attheir lower ends to the top of the reservoir A, so that the rod G willbe moved down and up at each revolution of the shaft J, and will thusdischarge the contents of the recess F to the surface to be oiled ateach of said revolutions.

To the shaft J is attached a ratchet-wheel, L, into the teeth of whichmeshes the engaging end of a pawl, M, pivoted to the pendulum N, so asto be operated by the swing of the said pendulum. The pawl M is madewith a weighted arm, 0, projecting in such a direction that the saidpawl will be heldin gear with the ratchet-wheel by the gravity of thesaid arm. The jar of the engine will be sufficient to keep the pendulumN in motion; but,

if desired, the said pendulum N may be extended into alever, asindicated in dotted lines swing of the pendulum N is limited by setscrews 1, which pass through screw-holes in the upper ends of thestandards Q. lhe lower ends of the standards Q are attached to the topof the oil-reservoir A, and the said standards Q are made of such aheight and their upper ends areinclinedinward at such an angle that thesaid set-screws 1 will be nearlyin the line of the are described by thependulumball, so that the said ball will strike squarely against theforward ends of the set-screws. However, the said set-screws may beadjusted as shown in Fig. 2. \Vith this construction the set-screws 1can be adjusted to cause the pendulum X at each swing to move theratchetwhecl Lthrough the space of more or less teeth, so as to increaseor diminish the time required for the said ratehet-wheelto make arevolution, and thus regulate the time between the successive dischargesof oil.

If desired, the oiler can be arranged in a horizontal position; but inthis case the rod (i must Work through a stufiing-box to prevent the oilfrom leaking out.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An oiler constructed substantially as herein shownand described, and consisting of the oil-reservoir provided with a tubehaving an opening in one side, and a jointed dischargerod having arecess in one side, and moved forward and back by a crank-shaft drivenby a ratchet-wheel, pawl, and vibrating pendulum or lever, as set forth.

2. In an oiler, the c01nbinati0n,with the oilreservoir A and the tube13, having side opening, 15, of the jointed extensible sliding rod G,having oil-receiving recess F between themai n part of said rod and theshoulder G of the extensible part, whereby the size of the recess F maybe regulated, and a driving mechanism, as set forth.

3. In an oiler, the combination, with the jointed oil-discharging rod G,of the crankshaft J, the atchet-wheel L, the weighted pawl 31, and thevibrating pendulum or lever N, substantially as herein shown anddescribed, whereby the said recessed rod will be operated at regularintervals to discharge oil, as set forth.

4:. In an oiler, the oitdischarging rod G, made, substantially as hereinshown and described, in two parts, halved to each other, connectedadjustably by screws,and having a recess, 1:, between the end of onepart and the shoulder of the other part,whereby the size of the saidrecess can be readily regulated,as set forth.
